I’ve worked in many London locations, including the City, Kensington, Kings Cross, Islington, Southwark, Shoreditch, Farringdon and the West End. I also work online with clients, with some projects a mix of online and onsite work and some projects entirely online.

Before working freelance in London, I also lived and worked in Zurich and Barcelona, with decent knowledge of German and Spanish languages.

Client Testimonials

We hired Pat to help with QA of a music streaming app. We needed someone with that magic “6th sense” of where the bugs are lurking; the ones which developers tend to miss. Pat more than fulfilled this need, with highly methodical approach and a great eye for detail.

Subsequently Pat has provided QA services for a personal app project of mine, finding a significant issue which had been lurking for some time.

Pat is a real asset to any team – highly competent technically but also easy going and a great guy to work with. Highly recommended!

Pat came to Composed to respond to our (increasingly urgent) need of QA on mobile and web and I can testify he more than fulfilled the task. On the Android side, his very structured approach (first exploratory testing, then focus on defining test plans for a variety of scopes) and his clear knowledge of the latest mobile technologies have quickly paid off. He was involved directly with the developers (including myself) and this very dynamic relationship enabled us to annihilate bugs swiftly and efficiently.

We’ve worked with Pat Walsh on a number of very different projects, from interactive video projects to mobile apps. His work is very thorough and has quickly become an essential and important phase of all the production work we do at Storythings. He’s thorough, diligent, and a pleasure to work with.

Pat is an excellent one-stop-shop for testing Apps and Websites. He is a self-starter who just knows what needs to be done and gets on with it, and is responsive to requests for any specific testing requirements. He provides test plans and reports as a matter of course and was a pleasure to work with. I will definitely be working with Pat again if the opportunity arises.

Pat performs comprehensive website testing for us, across all the main browsers and platforms, including mobile devices. His flexible approach to testing and clear feedback enable us to have confidence that the business end of our website is still working smoothly after system updates and changes.

Pat Walsh provided Kingston Valdes with a professional and personable service that was excellent value. The site was built and tested quickly, we are delighted with the results, and we have already had positive feedback from some of our clients. If you’re thinking of building a new site or adapting an existing one, I’d certainly recommend speaking with Pat about it.
